Home Addition Services in Richmond

Permits & Regulations

The City of Richmond requires building permits for all home additions through its Building Approvals department. Applications are submitted online or in person at Richmond City Hall (6911 No. 3 Road). A typical single-storey addition permit application requires architectural drawings, structural engineering plans, a geotechnical report (mandatory for most Richmond properties due to soil conditions), and an energy efficiency compliance report per the BC Energy Step Code. Permit fees are calculated based on construction value, generally ranging from $12 to $15 per $1,000 of project value, with a minimum fee. For a typical addition valued at $150,000–$300,000, expect permit fees of $2,000–$5,000. Processing times for addition permits in Richmond typically range from 6 to 10 weeks for straightforward projects, though complex additions or those requiring variances can take 12 to 16 weeks or longer. A Development Permit may also be required if the property is in a designated development permit area, which covers much of Richmond. Homeowners should also budget time for the required geotechnical investigation, which should be completed before the permit application is submitted. The City of Richmond enforces strict Flood Construction Level requirements, so all permit drawings must show compliance with the designated FCL for the property's location. Inspections are required at multiple stages including footing/foundation, framing, insulation, and final occupancy. Richmond building inspectors pay particular attention to moisture barriers, drainage systems, and seismic connections given the city's unique soil and flood plain conditions. Homeowners should also check whether their property falls within a heritage conservation area or is subject to any restrictive covenants that could affect the addition design. All home addition work must comply with the BC Building Code and applicable municipal bylaws.
